3.37 Ct. White Cabochon Sapphire from Ceylon (Sri Lanka)

One beautiful semi translucent 3.37 carat oval shape white sapphire, measuring 8.65 x 8.16 x 4.42 mm, presents a cabochon cut that emphasizes a smooth domed surface and the stone character rather than faceted brilliance. The gem is graded included for clarity when evaluated at eye level, with a near colorless color intensity and an excellent polish. The material is unenhanced, retaining its natural state, and is of Ceylon origin from Sri Lanka. As a corundum family gem with a hardness of nine on the Mohs scale, this sapphire offers strong physical durability for everyday wear when set appropriately. The cabochon form and the included clarity create a gem with personality and depth, offering translucency and internal structure that respond distinctively to different lighting environments.

Under cool daylight and neutral natural light, this sapphire reads as near colorless with a soft internal glow, the semi translucency allowing transmitted light to diffuse through the dome and illuminate internal features. In open shade and overcast daylight the stone shows gentle tonal variation, with milky and silvery areas contrasted against clearer windows where light passes more freely, and surface reflections remain crisp because of the excellent polish. In direct sunlight the stone gains greater contrast, internal inclusions and mineral clouds become more apparent, and small reflective highlights appear on the dome surface, producing a lively interplay between surface sheen and internal scattering. Under warm incandescent light and warm tone LED light, the overall appearance trends slightly warmer, with amber and champagne tinges becoming more noticeable within the included areas, and the cabochon gives a soft glowing presence rather than sharp flashes. Under cool fluorescent or cool white LED lighting the stone can take on a more neutral to cool expression, with internal features appearing more subdued and the surface reflections appearing whiter. In low light and candlelight the sapphire exhibits a subdued, intimate luminosity, the dome acting as a lens that concentrates softer light back to the eye, and the result is a gentle, satiny sheen that emphasizes the gem s natural translucency rather than faceting sparkle.

The cabochon profile and included clarity make this sapphire particularly well suited to settings that allow light to enter and reveal its internal character, for example open back settings, low profile bezels with an open pavilion, or pendant mounts that permit light to pass through the stone from multiple angles. The 3.37 carat weight and the oval dimensions provide versatility for use in a statement ring or as a singular pendant focal point, and the excellent polish ensures attractive surface highlights in any mounting. Because the stone is natural and untreated, its value proposition rests on documented origin and natural state, qualities that are important to buyers seeking authenticity. Routine care consists of cleaning with warm soapy water and a soft brush, rinsing and drying with a soft cloth, and avoiding abrupt temperature changes and exposure to harsh chemicals, with professional inspection recommended after setting.
